摘要: Ignition quality tester (IQT) derived cetane numbers (DCNs) of binary blends each individual alcohol (1-, 2-, iso-, and t-butanol ethanol) with second component (n-heptane a real distillate fuel) have been measured to explore the autoignition behavior these mixtures. This study pays particular attention effect physical property variation within among families mixtures on their apparent reactivities. The relative reactivities are dominated by chemical kinetics, while blend-specific properties affect ignitability only slightly. results firmly support DCN measurement as means characterizing mechanistic ignition chemistry behaviors fuels blends. Surprisingly, t-butanol, which has shown in other studies be least reactive pure C4 alcohol, shows suppression reactivity when blended heptane or diesel fuel for most mixture fractions. result is related lack easily abstractable H...
